        riscv64: drop MAXPHYSMEM_128GB

        The MAXPHYSMEM config options have been removed upstream via the
        following commit, so we drop our setting.

               riscv: Get rid of MAXPHYSMEM configs

               commit db1503d355a79d1d4255a9996f20e72848b74a56 upstream.

               CONFIG_MAXPHYSMEM_* are actually never used, even the nommu defconfigs
               selecting the MAXPHYSMEM_2GB had no effects on PAGE_OFFSET since it was
               preempted by !MMU case right before.

               In addition, the move of the kernel mapping at the end of the address
               space broke the use of MAXPHYSMEM_2G with MMU since it defines PAGE_OFFSET
               at the same address as the kernel mapping.
